Control device of lighting devices, motors, solenoids or heating bodies connected by AC single line

The invention discloses a control device of lighting devices, motors, solenoids or heating bodies connected by an AC single line. The control device comprises a control receiving part and a switching part or a switch functional part. When the control device is used for controlling the lighting devices, the motors, actuators or the heating bodies connected by the AC single line by means of switches, the control device can perform action control on colors, brightness, time and a scene sequence of the lighting devices or can perform selection control on the plurality of lighting devices in addition to a simple On/Off operation. If loads are motors, the control device can control actions of rotation starting/stopping, rotation speeds, rotation amounts, rotation time, rotation directions, and a scene sequence of the motors, control timed actions or perform selection control on the plurality of motors. The actuators can control the solenoids so as to control a displacement amount of a set object. The heating bodies
